Abstract [sv]

Syftet med den här studien är att bedöma säkerheten och motståndskraften hos ett Matter-protokoll som används av ett multinationellt företag. Protokollet används för att möjliggöra kommunikation mellan en gateway och en applikation för styrning av smarta produkter. Utvärderingen inleddes genom att ansluta en gateway till ett nätverk och installera operativsystemet Kali Linux på datorn. Därefter utfördes flera DoS-attacker med varierande intervall, antal paket och paketstorlekar. Dessutom genomfördes en Man in the Middle-attack för att bedöma säkerheten och försöka attackera protokollet för att uppnå säkrare resultat. Resultaten från de första DoS-attackerna visade att applikationen kopplades bort från företagets gateway efter att den attackerats med ett specifikt TCP-paket. Applikationen tappade kontakten med gateway när den utsattes för en viss mängd skickade paket. Vid de efterföljande DoS-attackerna visade resultaten att gatewayen tog tid innan den reagerade. Studiens slutsats indikerar således att Matter-protokollet uppvisar dröjsmålseffekt vid DoS-attacker där gatewayen inte omedelbart reagerar. Dessa observationer har betydelse för protokollets säkerhetsaspekter och kan leda till rekommendationer för att förbättra dess motståndskraft mot olika attacker.

Abstract [en]

The purpose of this study is to assess the security and resilience of a Matter protocol used by a multinational company. The protocol is employed to facilitate communication between a gateway and an application for the control of smart products. The evaluation commenced by connecting a gateway to a network and installing the Kali Linux operating system on the computer. Subsequently, multiple Denial-of-Service (DoS) attacks were conducted with varying intervals, packet quantities, and packet sizes. Additionally, a Man-in-the-Middle attack was executed to assess security and attempt to compromise the protocol for more secure results. The results from the initial DoS attacks revealed that the application was disconnected from the company's gateway after being targeted with a specific TCP packet. The application lost contact with the gateway when subjected to a certain number of transmitted packets. In the subsequent DoS attacks, the results indicated a delay in the gateway's response. The study's conclusion suggests that the Matter protocol exhibits a latency effect during DoS attacks, where the gateway does not respond immediately. These observations have implications for the security aspects of the protocol and may lead to recommendations for enhancing its resilience against various attacks.
